# AgentLayer - [Overview](/docs): One folder, one agent, a brain that compounds. The AgentLayer agent, documented on the three layers it is built from. - Getting started - [Install](/docs/getting-started/install): Prerequisites and the plugin install on each host. - [Onboarding](/docs/getting-started/onboarding): What the init wizard asks, what it writes, and the one convention every session depends on. - [Your first session](/docs/getting-started/first-session): What a session looks like from launch to exit, and where the context comes from. - [Updating](/docs/getting-started/updating): Pull a new plugin version, then reconcile your home with the upgrade skill. - Platform · Context - [The platform is the brain](/docs/platform): Layer 01. Everything the agent knows, captured from real work and compiled into files it loads before every session. - [The agent home](/docs/platform/agent-home): One folder holds everything that makes Kevin yours. Here is what lives where. - [The brain](/docs/platform/the-brain): Raw conversations are source code, the model is the compiler, and the compiled wiki is your queryable second brain. - [Capture](/docs/platform/capture): Feed the brain anything. Thoughts, files, URLs, clipboard, and corrections, from chat or the terminal. - [Sync](/docs/platform/sync): One pass through every maintenance operation, in dependency order, ending in a status line and an optional next move. - [Self-evolution](/docs/platform/self-evolution): Corrections become learnings, learnings load every session, and a review skill turns recurring signals into prompt and skill edits. - [Seed bundles](/docs/platform/seed-bundles): Hand an agent's persona and setup to a teammate as a zip, or start one from the web wizard. Memory, sessions, and credentials stay the recipient's own. - [Multiple agents](/docs/platform/multiple-agents): One plugin install, several homes. Personal, work, and specialist agents that never share a brain. - Agent · Harness - [The agent is the harness](/docs/agent): Layer 02. The agent that loads the context every session, and the rails around the model that make it safe to use. - [Hosts](/docs/agent/hosts): Kevin runs inside an agent CLI you already use. The home is the same on every host; what differs is how the host is wired to it. - [Claude Code](/docs/agent/claude-code): The first host. Bundled hooks and MCP server, the sandbox and permission model, memory routing, and running homes on separate accounts. - [Codex](/docs/agent/codex): Run the same home from OpenAI Codex. Per-home hooks and MCP registration, a permission profile generated from the home's settings, and the limits that remain. - [Hooks](/docs/agent/hooks): The four moments the plugin hooks into, on either host, and what each one does. - [Configuration](/docs/agent/configuration): Environment variables, where secrets live, and the Database and GitHub packs. - [Tasks and projects](/docs/agent/tasks): Markdown-native task management. One file per task, YAML frontmatter, threads as callouts, a generated dashboard. - [Daily rhythm](/docs/agent/daily-rhythm): The cadence skills. Briefings, pulses, standups, session radar, and the goals ladder. - [Worktrees](/docs/agent/worktrees): Parallel agents on one repo with zero collisions, and a skill that creates and bootstraps the checkout for you. - [Architecture](/docs/agent/architecture): The brain is portable markdown. The host is the runtime. The plugin is the glue. - Modules · Powers - [Modules are the powers](/docs/modules): Layer 03. What the agent can do and what it can reach. Skills, MCP tools, and the packs that switch on with a credential. - [Plan and run](/docs/modules/plan-and-run): The work. Projects, tasks, the roadmap, the goals ladder, briefings, and the session radar. - [Build and ship](/docs/modules/build-and-ship): The code. Worktrees, pull-request review, API collections, deploy checks, plan specs, releases. - [Reach and see](/docs/modules/reach-and-see): The world. The browser, logs and uptime, the database, search, chat, the support desk, and the SEO suite. - [Brain and memory](/docs/modules/brain-and-memory): The context. Capture, compile, self-review, sync, the dashboard, seed bundles, and onboarding. - [Skills](/docs/modules/skills): All 39 skills, one line each. Core skills load always; pack skills activate through configure-skills. - [MCP tools](/docs/modules/mcp-tools): The 56 tools the kevin MCP server exposes, grouped, with what is pre-granted and what always asks. - [Browser tools](/docs/modules/browser): Screenshots, styled PDFs, page-to-Markdown, recordings, and scripted flows, backed by a bundled Chromium. - [SEO workflow](/docs/modules/seo): Search Console, PageSpeed, SerpAPI, and OpenPageRank behind six read-only skills and one composite audit. - [External accounts and costs](/docs/modules/accounts): The core needs zero external accounts. Packs add optional services, most of them free. - Dashboard - [Dashboard](/docs/dashboard): A self-contained mission-control page, regenerated from the home, that shows all three layers as one screen. - Reference - [CLI](/docs/reference/cli): bin/kevin runs the MCP server's logic from a plain terminal, for cron jobs, scripts, and one-shots. - [Upgrades and releases](/docs/reference/upgrades): Maintainers release, consumers upgrade, and the CHANGELOG is the contract between them. - [Naming your agent](/docs/reference/naming): The plugin is agent-kevin. Your agent does not have to be called Kevin. - [Changelog](/docs/changelog) - Workstation - [The rig](/docs/workstation): Optional. Running agents well is less about the model and more about the terminal, the keybindings, the worktrees, and where the brain lives. - [Terminal](/docs/workstation/terminal): Ghostty, the keybindings that pay for themselves, and the one Claude Code flag to turn on. - [cmux](/docs/workstation/cmux): A native-Mac terminal built on Ghostty for running many agents at once, with a sidebar that shows who is waiting. - [Editor and tools](/docs/workstation/editor-and-tools): VS Code as the viewer, Obsidian as the brain reader, MarkEdit for documents, Tower for git review. - About - [Privacy](/docs/about/privacy): All data stays local. Secrets are deny-gated. Transcripts are redacted before they persist. - [Platforms and limits](/docs/about/platforms): Built and tested on macOS. Linux and Windows work with a few caveats. Some limits are by design. - [FAQ](/docs/about/faq): Short answers to the questions that come up first. - [What Kevin used to be](/docs/about/history): Kevin started as a daemon with a Telegram bot. Subscription billing rules turned it into a plugin. - [Contributing](/docs/about/contributing): Pull requests welcome. Open an issue first for anything architectural.
